ContractorSelling.com is holding three-day customer service “boot camps” aimed at HVAC and plumbing contractors in Los Angeles this summer.

Led by Joe Crisara, the sessions will explore how to change thinking to grow business. Topics will include loyalty programs, telephone campaigns and social media reviews. The sessions will take place July 17-19, Aug. 7-9 and Sept. 11-13. The sessions will be streamed live on the internet.

 Contractors who that already taken the course have good things to say about it, according to program officials.

“This is the best career investment that I have ever done,” said Rocky Cocciolo of Shamrock Heating and Cooling. “This system has truly maximized every aspect of world class service, which has had the maximum impact on my clients and personal effectiveness.”

David Mendenhall, Owner of Tri-M Plumbing, had similar comments.

“Not only have my sales abilities rocked, my staff has shown consistent improvement in their numbers,” Mendenhall said. “More importantly, their customer service has improved exponentially!”
